Every time that Krystal Kohler appears as bad seed Mary Tilford, an electric charge surges through the Shadow Show Theatre Company's staging of "The Children's Hour." It's a disturbing, terrific performance, and one of the elements that contribute to a solid debut from the new troupe.

"The Children's Hour" can be seen through Aug. 29 at the SAY Si Theater. Visit the Shadow Show Web site for more info.
